Design and Analysis of Cylindrical Dielectric Resonator Antenna for 5G Application

DRA’s are used for 5G communications of large bandwidth at sub 6GHz and millimeter to Terahertz. The channel capacity can achieve a very high data rate i.e. C=Blog2(1+SNR) where C is the channel capacity and B is the bandwidth of the channel. The cylindrical resonator antenna operating in hybrid HEM11⸹ mode. In this paper a cylindrical dielectric resonator antenna(CDRA) with frequency range (2-6GHz).The cylindrical dielectric resonator with radius r=10mm and height h=10mm. the CDRA material is alumina ceramic with a permittivity of εDRA is 9.9 and the resonant frequency is fr=4GHz. The substrate will be is Rogers RT 5880 with εr=2.2 and tan⸹=0.0009, the thickness is 1.52mm. The CDRA is excited about the microstrip line. so the cdra is coupled electromagnetically by this microstrip line and below the substrate, we have a ground plane with annealed alumina so we have no radiation or low below the substrate all the radiation is top of the CDRA. The proposed antenna is simulated using CST microwave studio software and the designed antenna will operate for 5G applications and we can consider massive MIMO antenna array configurations. This design analyses the parameters of CDRA
